Description

Technical Field

[0001] The utility model relates to the technical field of petroleum analysis devices, in particular to a petroleum carbon content analyzer. Background Art

[0002] The analysis of carbon content in oil is of great significance for the evaluation of oil quality and industrial production. The carbon content in oil is closely related to its combustion characteristics. By analyzing the carbon content, we can understand the combustion calorific value, combustion stability and emission of combustion products of oil, so as to evaluate the performance of oil in energy utilization; as an industrial raw material, oil needs to consider its carbon content in many processing processes. For example, in the process of oil refining, the carbon content of oil will affect the operating conditions and product quality of the processing, so it is necessary to analyze the carbon content of crude oil to guide production operations; for oil products used as fuel, such as gasoline, diesel, etc., their carbon content is directly related to the combustion efficiency, environmental emissions and engine performance of the fuel. Therefore, analyzing the carbon content of oil products can help monitor fuel quality; the emissions generated by oil combustion contain carbon compounds such as carbon dioxide, which have an impact on the environment. By analyzing the carbon content in oil, the environmental impact after combustion can be evaluated, which is helpful for environmental protection and monitoring; the common oil carbon content analyzer is called elemental analyzer or carbon sulfur analyzer. This instrument is used to accurately measure the carbon content in oil samples; carbon sulfur analyzers usually use high temperature combustion-infrared detection technology. Its working principle is to burn the organic matter in the petroleum sample into carbon dioxide, and then use infrared spectroscopy technology to measure the content of the generated carbon dioxide, so as to obtain the content of carbon in the sample; under normal circumstances, when analyzing petroleum combustion, it is necessary to quantitatively measure the burning petroleum, and the means of transporting petroleum samples usually need to be quantitative. The conventional means use a measuring cup and the oil remaining in the measuring cup will cause the final measurement to be inaccurate, thus affecting the final measurement result. Therefore, this case hopes to propose a petroleum content analysis instrument that can automatically pump petroleum samples, and quickly and automatically pump equal amounts of samples when a comparative measurement is required after a measurement. While facilitating measurement, it can also quickly carry out secondary measurements, improve measurement efficiency, and make the results inaccurate and thus affect the measurement and analysis results. For the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, the utility model is implemented through the following technical solutions: a petroleum carbon content analyzer, comprising: an instrument housing, a sample feed port and a control combustion chamber, the sample feed port is installed on the instrument housing, the control combustion chamber is opened in the instrument housing, a grating-assisted peristaltic structure is installed in the instrument housing, and a detection auxiliary component is installed on the control combustion chamber;

[0004] The grating-assisted peristaltic structure includes: a quantitative driving chamber, a core traction block, a body joint fitting tube, a pair of pump tube compression keys, a pair of key body positioning blocks, a pair of delivery joints, a micro-motion rotary pump motor, a grating photoelectric composite emission detector and an atomizing nozzle;

[0005] The quantitative drive bin is installed in the instrument housing through a bracket, the micro-motion rotary pump motor is installed in the instrument housing through a bracket, and the micro-motion rotary pump motor is connected to the core traction block through a rotating shaft, a pipeline coupling connection groove is opened in the quantitative drive bin, the healthy body connection fitting tube is installed in the quantitative drive bin through the pipeline coupling connection groove, the core traction block is installed in the quantitative drive bin, and the core traction block is respectively connected to a pair of the pump tube compression key bodies, a pair of the pump tube compression key bodies are respectively connected to the healthy body connection fitting tube, a pair of the key body positioning blocks are respectively installed on a pair of the pump tube compression key bodies, and a pair of the key body positioning blocks are respectively opposite to the grating photoelectric composite emission detector, the grating photoelectric composite emission detector is installed in the instrument housing through a bracket, a pair of the delivery adapters are respectively installed at both ends of the healthy body connection fitting tube, and a pair of the delivery adapters are respectively connected to the sample feed port and the atomizing nozzle through a conduit, and the atomizing nozzle is installed in the control combustion chamber.

[0006] It should be noted that, in the above, the sample oil is put into the sample feed port, the dustproof compartment door provided on the sample feed port is closed, and the micro-rotary pump motor in the instrument housing rotates, driving the core traction block in the quantitative drive compartment to rotate, thereby driving a pair of pump tubes to compress the key body to rotate and compress the healthy body joint fitting tube in turn, so that the sample oil gradually flows from the direction of the sample feed port to the direction of the atomizing nozzle. The delivery connector is responsible for connecting the healthy body joint fitting tube and the conduit until the oil sample is delivered to the atomizing nozzle, and then the sample oil is atomized and sprayed into the control combustion chamber to facilitate subsequent combustion measurement. The grating photoelectric composite emission detector can emit a grating to a pair of key body positioning blocks and detect its movement amplitude. Because the volume of the healthy body joint fitting tube is fixed, each time the pump tube compresses the key body, a certain amount of sample oil will be squeezed out. According to the movement amplitude of the pump tube compressing the key body, the amount of sample oil extruded and delivered can be accurately calculated, and thus combined with computer analysis and calculation, the amount of sample oil delivered to the atomizing nozzle can be accurately inferred according to the positioning detection of the grating, thereby realizing the measured amount of quantitative delivery and measurement of the sample.

Only after reaching the set amount will the sample oil be sprayed and ignited and burned through the igniter. Because the spraying amount of the sample oil and the oxygen content in the combustion chamber are fixed, the combustion data is more reliable and more accurate. The carbon dioxide concentration detection element analyzes and detects the carbon dioxide content after combustion, and transmits the data to the integrated analysis base station through a data cable. The integrated analysis base station integrates and transmits the data to the computer base station for easy analysis and comparison, thereby accurately analyzing the carbon content of the sample oil and issuing a report.
